PATENT OFFICE JAMES HOWARD RICHARDS, OF CARROLLTON,

OHIO I HElflSUED Application filed September 19, 1927. Serial No.220,394.

The present invention relates to a bottle cap and cork for use-onbottles designed for receiving the usual crimped cap, the presentcombined cork and cap being used either as a replacement for a bottlewhen opened and partially used or for original use in sealing thebottle.

The present cap and cork is so designed as to provide a cork which willfit snugly and grip the interior neck surface of a bottle as well as toprovide a cap portion adapted to engage over the usual flange or bottlemouth ring and thus combines the functions of an outside engaging capwith a cork portion and the unit is so made as to furnish a tight sealfor bottles having a charged content. To the accomplishment of theforegoing and related ends, said invention, then, consists of the meanshereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawing:

Fig. 1 is a vertical sectional view showing a combined cap and cork inplace in a bottle neck; Fig. 2 is a View similar to Fig. 1. but showinga slightly modified structure; Figs. 3 and 4 are sectional views of thecaps and corks shown in the bottle necks in Figs. 1 and 2 respectively;Figs. 5 and 6 are sectional views of modified forms of the corks shownin Figs. 3 and 4 respectively.

In Figs. 1 and 2the usual type of bottle neck is shown, this neck 1having an outwardly bulging portion 2 with an outer portion 3 of reduceddiameter and terminating at the top in aislightly overhanging flange orrim 4. The interior of the neck has an enlarged portion 5 correspondingwith the bulge 2 onthe outside.

The present combined cap and cork as shown in Figs. 1 and 3, provides acork portion 10 slightly ta ered 1n general shape but having an enlargering or flange 11 adjacent the bottom, the length of-the cork portionbeing sufiicient to allow the flange 11 to seat itself in the enlargedportion 5 of the bottle neck when the cork is forced into the bottle. Inthe form shown in Figs. 1 and 3 the bottom of the cork is concaved as at12 and thus when in place in the bottle, the internal gas pressure tendsto expand the sides of the corkincluding the ring 11 into the enlargedbottle neck 5, thus aiding the seal. In the form shown in Fig. 5, theend of the cork is convex rather than concave. In both cases the ring.portion 11 of the cork tapers slightly as does the upper portion 14 asthis aids in forcing the cork into position. i

The upper portion of the combined unit comprisesa disc-shaped top 15for-med integrally with the cork 10, and this disc portion has adownwardly extending outwardly flaring flange 16 which terminates in aninwardly extending ring portion 17 formed with an upwardly beveled loweredge 18. This flange 16 is sufliciently long to allow the ring 17 toengage under the upper bulge 2 of the bottle neck where it engagessnugly much in the same manner as the usual crimped cap except that thepresent cork is made of a resil ient material such as rubber and issprung or forced into engagement. In the form shown in Figs. 2 and 4,the cap and cork are similar to the first form inall respects save forthe cork portion 20 which in this form tapers from top to bottom and isprovided at a point so as to engage in the enlarged portion 5 of thebottle neck, with an encirclin bead or ring 21. The bottom 22 of the cormay be either convex as shown in Figs. 2 and 4, or maybe hollowed out asat 23, shown in Fig. 6.

The inwardly beveled edge 18 on the cap portion of the cork allows thecap to cam itself into engaging positionover'the bottle neck and-at thesame time aids in easy removal as it forms a finger grip so that oneside ma be moved up and over the top bulge of the ottle when the furtherremoval is easily accomplished. a

It has been found that with the extra flange or ring on the cork portionadapted to seat tightly in the interior enlargement of the bottle neckthat the present eombined cap and cork will hold under relative high gaspresrubber producing t e most, satisfactory results. These units may beused repeatedly, and until their resiliency is lost, will efi'ectivelyseal the usual type of bottles-holding .charged beverages such as gingerale, near beer, and the like, without the loss of eitherliquid or gas.

Other modes of applying the principle of our invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.-

We therefore particularly point out and distinctly claim as ourinvention:

1. A combined rubber bottle cap and cork consistin of a cork portion inthe form of an elongate slightly tapering plug, said plug having anenlarged ring adjacent the lower end, said plug having a concave bottomsurface of a depth not exceedin that of said enlarged ring and anintegral y formed cap member having an outwardly and downwardlydepending flange terminating in an inwardly extending thickened ringportion,

said flange and ring portion beingadapted to be forced over and aroundthe bottle neck to bring said ring portion into elastic engagementtherewith below the upper head.

2. A combined {rubber bottle cap and cork consistin of a cork portion inthe form of an elongated sightly tapering plug, said plug having anenlarged ring adJacent the lower end, said ring bein also slightlytapered and being so positione as to normally engage in the enlargedportion of a bottle neck, said plug having a concave bottom surface of adepth not exceeding that of said enlar ed ring, and an integrally formedcap mem er having an outwardl and downwardly de-' pending flangeterminating in an inwardly extending ring portion, said flange and ringportion being adapted to be forced over and around the bottle neck tobring said ring portion into elastic engagement therewith below theupper head.

3. A combined rubber bottle cap and cork consistin of a cork portion inthe form of an elongate sli htly tapering plug, said plug having an enarged ring ad'acent the lower end, said ring being also slightly taperedand being so positioned as to normally engage in the enlarged portion ofa bottle neck, said slug having a concave bottom surface of a epth notexceeding thatof said enlar ed ring, and an integrally formed cap mem erhaving an outwardly and downwardly de- Signed by us this 15thday ofAugust, 1927. 7
